Patients underwent one or two courses of combination pharmacological therapy, described under Patients and methods. At microbiological eradication (T1), the antibacterial agents were discontinued and the remaining compounds were administered for a period of 6 months, up to time point T2. (A): Urine peak flow rate (Qmax); T1 vs. T0, P = 0.0022; T2 vs. T0, P = 0.00013. (B): Bladder percent voided volume; T1 vs. T0, P = 0.0056; T2 vs. T0, P < 0.0001. Paired t-test.
